As a person who's been trying to work on businesses for years and not finding success, I'm gonna keep going.
I'm not religious but one the most interesting things I've read on this topic is titled "Invest in Many Ventures" in the book of Ecclesiastes. The 6th and final verse says:
"Sow your seed in the morning,
and at evening let your hands not be idle,
for you do not know which will succeed,
whether this or that,
or whether both will do equally well."
So if one thing doesn't work, try something else. Also be open to investing in different projects at the same time because you don't know what will succeed. 10[reply]
